fix iterating over fundamental types.
Tue Sep 2 14:53:41 2003 Tim Janik <timj@gtk.org> * gobject-query.c (main): fix iterating over fundamental types. * gtype.c: applied patch from owen which keeps internal class initialization state to maintain class and interface initialization happen in the order of: 1. class' base_init 2. interface' base_init = interfaces added after here are immediately base_init-ialized 3. class_init 4. Interface_init = interfaces added here are immediately Interface_init-ialized
